Where do freshwater eels come from? Aristotle claimed they sprang straight from river mud, and some people thought they grew from bits of skin, or even horsehair. In 1896 an Italian discovered that a tiny ‘saltwater fish’ was in fact the larva of the freshwater eel. We are gradually learning more about their remarkable life journey, which begins and ends in the ocean.
